Carnival shuttle is a period 12 oscillator that was found by Robert Wainwright in September 1984 (using middleweight emulators at the end, instead of the monograms shown here). It was used to create the first known non-trivial period 24 oscillator, 186P24.

The shuttle itself is a reaction between two t-tetrominos. Its stability requires the suppression of one birth per period at both ends of the shuttle.

There are many ways to stabilise adjacent shuttles:

  • Monograms can be shared.
  • Shuttles can be placed head to head.
  • A beehive can be placed in between.

Shuttles can also hassle a beehive-traffic light-loaf component. The shuttle can be stabilised by monograms, middleweight emulators and T-nosed p4s. The Blocked p4-3 gives the same spark, and thus can be used as a stabilizer too.

Without sparkers on the ends, a spatial period 12 wick can be constructed. A finite version requires the addition of sparker oscillators as caps.
